There's a long pause while Bobby tries to distinguish that time from all the others. "Was that the time in the bathroom of the club or when we ended up at mine?" For some reason, John's sentences calm him, like he now knows he's not alone at this time in the morning, that there is someone real to talk to instead of just inside his head. Well, someone real that he wants to talk to, Penelope doesn't count.
He totally ignores the mention of work. John's here now, he won't abandon him to sleep, no way, not if Bobby doesn't mention it. "I only remember finding out your name the second time, so that was at mine." He remembers now, calling John's name hoarsely in sweaty sheets twisted around their bodies. And now his breath is back to normal, and he stops twisting his fingers in his hair and returns to sucking on his butt, attempting smoke rings.
